The utility model discloses a water intake and drainage system, refer to fig. 1 and 2, including first casing 100, level detector 200, control module and water feeder 300, first casing 100 is injectd to have cavity 110, cavity 110 includes first drainage chamber 111, second drainage chamber 112 and limbers 113, first drainage chamber 111 is linked together through limbers 113 and second drainage chamber 112, wherein, first drainage chamber 111 forms inlet opening 1111 at the top of first casing 100, second drainage chamber 112 forms apopore 1121 at first casing 100, wherein, inlet opening 1111 is higher than limbers 113, and the inner port of apopore 1121 is higher than limbers 113; the water level detector 200 is disposed at the first housing 100, and detects a water level of the chamber 110; when the water level detector 200 detects that the water level of the cavity 110 is at the first set value, the control module controls the water feeder 300 to be automatically opened to supply liquid water to the cavity 110 until the liquid level of the cavity 110 is equal to or higher than the water through hole 113, and at this time, the liquid water in the cavity 110 seals the water through hole 113.

Specifically, since the water inlet 1111 of the first drain chamber 111 is higher than the water passage hole 113 and the inner end of the water outlet hole 1121 of the second drain chamber 112 is higher than the water passage hole 113, the liquid water in the chamber 110 can be higher than the water passage hole 113. When the liquid water in the cavity 110 is equal to or higher than the water through hole 113, the liquid water in the cavity 110 seals the water through hole 113, so that the deodorization effect is achieved. When the water inlet and outlet system is not used for a long time and the liquid water in the cavity 110 is at the first set value, i.e. the position of the water through hole 113, at this time, the liquid water in the cavity 110 cannot achieve the effect of water sealing the water through hole 113. Through the setting of water level detector 200 and control module group, when water level detector 200 detected the water level in cavity 110 at first setting value, water feeder 300 can be opened automatically under control module group, and water feeder 300 supplies liquid water to cavity 110, makes the water level in cavity 110 be higher than limbers 113 to reach the effect of water seal limbers 113 once more, and then reach deodorant effect.

In some embodiments, the water supply 300 may be of various types, for example, the water supply 300 is a control valve connected to a pipe on the tub 10.

Further, when the water level detector 200 detects that the water level in the cavity 110 is higher than or equal to the second set value, i.e. higher than the position of the water through hole 113, the water feeder 300 is automatically turned off to stop supplying liquid water to the cavity 110, thereby avoiding excessive liquid water addition and waste of liquid water. Of course, the control of the closing of the water inlet and outlet system is not limited to the above-mentioned one, and for example, another sensor may be provided at the water outlet of the water inlet and outlet system, and the water inlet and outlet device 300 stops supplying the liquid water to the chamber 110 when the sensor senses that the liquid water is discharged from the water outlet.

In some embodiments, the water inlet and drain system further includes a lower cover 116, the bottom of the first casing 100 defines a lower opening 114, the lower opening 114 is communicated with the cavity 110, and the lower cover 116 is screwed to the first casing 100 for closing the lower opening 114. The inner wall of the first case 100 is provided with a partition 115, the partition 115 divides the chamber body 110 into a first drain chamber 111 and a second drain chamber 112, and the partition 115 is spaced apart from the lower cover 116 to form a water passage hole 113 communicating the first drain chamber 111 with the second drain chamber 112. It will be appreciated that when the chamber body 110 is blocked, particularly at the position of the water passage hole 113, the first and second drain chambers 111 and 112 and the water passage hole 113 can be cleaned by removing the cover 116, thereby preventing the blocking of the water supply and drainage system.

Further, the water level detector 200 is disposed on the lower cover 116, so that the water level detector 200 is convenient to mount and dismount, and the subsequent maintenance of the water level detector 200 is facilitated.

In some embodiments, the water supplier 300 is connected to the first housing 100 through a pipe to directly supply liquid water to the cavity 110; alternatively, the water supplier 300 supplies liquid water to other members, such as a wash stand, the tub 10, or a toilet, etc., to be supplied into the first housing 100.

In some embodiments, the water intake and drainage system further includes a water drain 400, the first housing 100 is adapted to be connected to the bottom of the bathtub 10, the water intake 1111 is in communication with the interior of the bathtub 10, and liquid water in the bathtub 10 is drained through the first housing 100. The drain 400 is provided to the water inlet hole 1111, and the drain 400 is used to close or open the water inlet hole 1111. The water supply 300 is connected to an upper portion of a side of the tub 10 for supplying liquid water to the tub 10. When the water level detector 200 detects that the water level in the cavity 110 is less than or equal to the first set value, the control system controls the drain 400 to be automatically opened together with the water supply 300, the water supply 300 supplies liquid water into the bathtub 10, and the liquid water is drained from the bathtub 10 into the first enclosure 100, so that the water through hole 113 is sealed. The water supply 300 is used to discharge liquid water into the tub 10 to be discharged into the first housing 100, and the drain 400 is also used when the tub 10 is used. As can be seen from the above, compared with the case that the drainer 400 is directly discharged into the first casing 100, the structure of the water inlet and outlet system of the present application is simplified, and the manufacturing cost is reduced.

Meanwhile, when the flow detector detects that the flow in the delivery pipe 600 is less than or equal to the second flow value, which is about 0.2L/S, the control system controls the drain 400 to close automatically, so as to ensure that the water in the bathtub 10 can reach the connection position between the delivery pipe 600 and the bathtub 10, so that the user can take a bath subsequently.

In some embodiments, referring to fig. 1 and 3, the water supply and drainage system further includes a second housing 500 and a delivery pipe 600, the second housing 500 defining a water supply passage 511 and an overflow passage 521, the second housing 500 being adapted to be disposed in the tub 10, a water supply 300 connected to the second housing 500, a water outlet of the water supply 300 communicating with one end of the water supply passage 511, and the other end of the water supply passage 511 communicating with the tub 10, such that the water supply 300 supplies liquid water into the tub through the second housing 500; meanwhile, a transfer pipe 600 is connected between the first and second housings 100 and 500 and communicates with one end of the overflow path 521, and the other end of the overflow path 521 communicates with the bathtub 10, so that liquid water overflowing from the bathtub 10 is discharged into the transfer pipe 600 through the second housing 500, thereby being discharged into the first housing 100. As can be seen from the above, by the arrangement of the second casing 500, the water supply of the bathtub 10 and the overflow of the bathtub 10 are all completed through the second casing 500, so that the assembly of the water supply and drainage system is more convenient, and the water supply 300 and the conveying pipeline 600 are respectively connected with the bathtub 10, which guarantees the integrity and the beauty of the bathtub 10.
